#2

Goddammit, Windows, why call that function with a null pointer for the layout object??

Thanks, I guess I just need to add a null pointer test there. Presumably the layout was empty, so it decided not to bother creating one.

Still Crash

 hr = dwTextLayout->GetLineMetrics (nullptr, 0, &actualLineCount);

 

dwTextLayout is nullptr
